We bought the "medium" firmness mattress as that is the only firmness Sams sells in the store, and we needed the mattress quickly before guests came to visit. It is softer than i would like, but is still comfortable.

DO NOT BUY. After a month of use, this mattress was worse than the worn-out Nectar mattress I was replacing. I am a 240 lb side-sleeper. The hammock effect is so deep that I am waking up with knee pain from bending my leg sideways. Will have to replace it with another Nectar mattress before my knee is permanently ruined.

We have bought two of these twin size beds. The first one was medium softness for my college-aged daughter. She loves the bed. The edges were a little too soft when sitting on the side of the bed, but super comfortable for sleeping. When my daughter moved out, we bought the same mattress in firm. I was worried the firm would be too hard, but it's perfect for me. So comfortable. You really can't beat the quality and comfort of these beds.

Bought 3 years ago for spare bedroom. Light use for single sleeper. Developed lump in between centre and edge of bed. Mattress covering developed ripple in that area, can be felt under sheet and mattress pad as mildly annoying. Otherwise seemingly comfortable mattress.

This mattress is a quality product. Nice looking but most importantly, comfortable and affordable. We purchased the medium firm mattress. Some reviewers mentioned the sides collapse when you sit on the edge. That isn't exactly what happens, they do give way but it doesn't dump you into the floor. We've been sleeping on it for months now and get a great and comfortable night's sleep. Some reviewers said the mattress is not firm enough. We found that after sleeping on it for a while, our bodies sort of adjusted. This may not make sense, however, we have no back pain or discomfort due to a mattress that is too soft. My husband needs a certain amount of support due to mild back issues and this mattress delivers what he needs. It isn't too hot even with this summer's heatwave. I do recommend this mattress and would purchase it again.

I ordered two Twin XL mattresses, and the value for the price is absolutely excellent. The shipping was incredibly fast; they arrived within just one day of placing the order. ​As for the mattresses, I ordered one Medium and one Firm, and here is my experience: ​The Medium: It felt truly medium, but it leans slightly toward being a bit softer. ​The Firm: It is a little less firm than what I am used to. ​Honestly, though, their overall quality is excellent! The foam quality is great and provides excellent support. I suffer from some back pain, and this mattress has helped a lot—I now wake up in the morning with no pain. ​As for handling the boxes, the weight is moderate and not too heavy. One person can carry them, especially since the boxes have built-in handholds to make carrying easier, though having two people is definitely preferred for a smoother process. ​Overall, I highly recommend buying this. The value you get for the price is fantastic!

We bought this bed, medium firm king. It's not medium firm at all. We sink in the middle and wake up in pain from the back ache. We want return it but we bought it online and the store said we need to return it to a local store, ugh! I would not recommend for adults.

I'm about 210 lbs., and unfortunately this mattress was far too soft for me. I sank deeply into it, almost like lying on a bag full of pillows, and it provided little support or the much-needed spinal alignment, actually giving me a sore back. Based on my experience, I would only recommend it for a much lighter person, perhaps under 150 lbs. If you are heavier or have back problems, I would strongly consider a more supportive hybrid mattress instead. The return process was also much more difficult than it should have been. Because getting the mattress folded back up and secured, down three stories, into my car, and to the Conroe Sam's Club was a major undertaking, I specifically called the Conroe location on September 2, 2026, at 10:55 a.m. (two days before my return date) to confirm exactly what was required for the return. I was told that I only needed to bring the mattress, the box and wrapping it came with, and my receipt. I had actually seen information online suggesting that the mattress might need to be completely wrapped in plastic, which is precisely why I called ahead to verify. However, the employee I spoke with specifically confirmed that, for their location, the mattress did not need to be sealed in plastic and that I could simply bring it back with the original box, the original wrapping in the box but not wrapped around the mattress, and my receipt. I work as an insurance adjuster, so paying close attention to details and exactly what is said is a routine part of my job, and I specifically recall the instructions I was given. However, despite what I had been previously told, when I arrived at the store, I was told that the mattress had to be fully sealed in plastic and taped and that I might have to take it all the way back home. After speaking with four employees and repeatedly explaining that I had followed the instructions their own employee gave me over the phone, a manager finally arranged for someone to come outside and wrap it so the return could be completed. Ironically, the male employee who came outside to handle it said the mattress was fine as it was. I ultimately received my refund, but only after a frustrating ordeal that could have been avoided had I been given the correct information from the start when I called. Back to the mattress itself, I would strongly recommend researching whether this type of all-foam mattress is appropriate for your weight and support needs, as well as confirming the return requirements before purchasing.

This mattress was comfortable for about 3 months before completely turning to mush. I've had it for only a year and am already looking for something new. There's a massive divot where my hips are and I sink into the mattress. My BMI is considered “normal/healthy” so there's no reason for the mattress to be sinking the way it is. It is NOT friendly for side sleepers. Save your money and go with another mattress!

I bought this full size 12 inch high Membermark firm mattress from Sam's Club less than 2 years ago with an adjustable membermark base. I turned the mattress in all 4 positions but it lost its firmness and uncomfortable in flat position. I weigh 230 pounds. It has a 10 year warranty, but no idea how to act on it and with who.
